The Interval is one of SF’s more unique bars, and will instantly impress anyone you take simply by showing them you know it exists. During the day it has kind of a coffee shop vibe (with interior design that combines the offices of a chemistry professor and a Mission start-up), but serving a long and impressive cocktail list instead of caffeine. It’s a good spot for a solo drink, or for a small group after you pretended to exercise by walking around the Presidio.
